I assume you're talking about the type of robot platform shown here:
http://members.xoom.com/_XOOM/jknudsen/Synchronicity/Synchronicity.html
All four wheels travel the same amount regardless what direction the robot is
moving. So, you won't get much from using multiple rotation sensors except to
help average out error due to slippage of individual wheels.

You'd need to know the angle somehow, and compute distance times sine and
distance times cosine to get the X and Y delta values.
